HARMAN’s JBL Professional Revolutionary D2 Dual Driver at the Heart of new VTX Line Array Series

ANAHEIM, California – With today’s introduction of HARMAN’s JBL Professional VTX Line Array Series, JBL is also unveiling the D2 Dual Driver—the revolutionary device that makes the VTX Series’ dramatic improvements in high-frequency sound and performance possible.

The D2 Dual-Diaphragm Dual-Voice-Coil Compression Driver overcomes the limitations of conventional compression driver technology: limited high frequency extension due to mass of the diaphragm and voice coil, and distortion characteristics that arise due to dome breakup modes. Merging two compression drivers into a single, compact transducer with a single acoustical output, the D2 Dual Driver utilizes two voice coils, each with its own lightweight, polymer, annular diaphragm, its own magnet assembly, and its own specialized phasing plug. Instead of the large and ‘heavy’ single voice coil metal dome diaphragm of conventional compression drivers, D2 is driven by two light but strong voice coils, two motive “forces” instead of one, acoustically connected to a single exit chamber.

“With two smaller diaphragms and voice coils working on the same acoustical load, the VTX Line Array Series provides high efficiency and SPL, plus increased extreme high-frequency reproduction due to the smaller moving mass of each diaphragm and voice coil,” said Paul Bauman, Senior Manager, Tour Sound, JBL Professional. “The D2 Dual Driver is a radical departure from traditional compression drivers and represents a monumental breakthrough in loudspeaker system design!”

The two annular polymer diaphragms have the same radiating area as a conventional single dome, and overall output and power handling are dramatically increased due to the lower moving mass and enhanced heat transfer obtained with two separate voice coils. The result is a compact compression driver with dramatically improved efficiency, power handling, smoother, extended high frequency response and significantly lower levels of nonlinear distortion.

Well-validated by objective measurements, D2’s performance has also gone through exhaustive subjective listening tests, demonstrating its superior sound quality compared to traditional metallic, mono structure drivers. D2 provides an extreme output advantage over conventional systems allowing significantly higher array power density.

Compared to a conventional system, the D2 has double the number of voice coils and more than double the power handling, but with a 30 percent reduction in weight. This results in a dramatic increase in pure high frequency sound pressure levels in the same physical footprint. The power handling of the three D2 drivers used in the VTX V25 are each 200 watts per AES standard.

HARMAN’s JBL Professional Introduces Next Generation VTX Line Array Series at Winter NAMM 2012

ANAHEIM, California – HARMAN’s JBL Professional today announced the introduction of the VTX Line Array Series—a revolutionary product that builds on the company’s 65-year heritage of loudspeaker design innovation and groundbreaking technology development. Designed for portable and fixed-venue system operators alike, the VTX Series features JBL’s legendary sound quality coupled with the most advanced sound reinforcement technology and support available.

“Of all the achievements JBL has made over the years, the VTX Series stands as a milestone in the practical application of creative engineering,” said Paul Bauman, Senior Manager, Tour Sound, JBL Professional. “VTX truly represents the next generation in line arrays—an evolution of JBL’s industry-standard VERTEC® that heralds a new era in performance, system integration and user-friendliness.”

The first product from the VTX Line Array Series is the VTX V25—a full-size, 3-way, high-directivity line array element. The VTX V25 features two 2000W, 15-inch Differential Drive® woofers mounted in die-cast aluminum baffles, with four 8-inch Differential Drive mid-range transducers and three of the revolutionary new D2 Dual-Diaphragm Dual-Voice-Coil Compression Drivers mounted on a 3rd generation waveguide and patented RBI Radiation Boundary Integrator® assembly.

At the heart of VTX is the D2 Dual Driver, a revolutionary device developed by JBL that dramatically improves the sound and performance of high frequencies. D2 overcomes the limitations of conventional compression driver technology: limited high frequency extension due to mass of the diaphragm and voice coil, and distortion characteristics that arise due to dome breakup modes.

JBL’s patented Radiation Boundary Integrator combines the high frequency and mid-range sections of the VTX V25 so the transition across each band is uninterrupted, undistorted and seamless. A patent-pending, tuned resonant absorption chamber (TRAC) is integrated into the waveguide itself, effectively eliminating throat-related cancellations due to back pressure from the mid-range section. VTX’s refined RBI waveguide implementation provides improved horizontal coverage—broader and more stable.

The VTX Series draws from the expertise and integration of the entire range of HARMAN Professional audio technologies. As a result, in addition to the best sound possible, setup, tuning, networking and controlling the VTX Series is efficient, intelligent and truly a system solution. For example, the VTX Series features Crown Audio VRack DSP and amplification. VRack is a rugged touring rack fitted with three Crown I-Tech HD Series power amplifiers, power input panel, and custom-engineered input/output panels that is available in two configurations: VRack 12000 and VRack 4 x 3500 are loaded with three IT 12000HD and three IT 4 x 3500HD amplifiers, respectively.

Apart from the performance advantage of a standard package ensuring that VTX Series enclosures are optimally powered and processed, VRack ensures compatibility for cross rental between VTX Network Partners. Since VRack is supplied with all components installed and internally connected, there is also no need for laborious rack building; no chance that a component might be improperly connected; and a dramatically lower chance of connection failure.

The patented workflow paradigm of the Performance Manager interface guides the system designer through the complete system design, configuration and control process and, in many ways, the entire process feels and acts like a simple step-by-step wizard.

Using HARMAN’s JBL HiQnet Performance Manager™ control software and with reference to measured spatial response, circuit level gain and JBL Line Array Control Panel tapering adjustments are performed as a first step in system tuning with the VTX V25. Once SPL and frequency response has been optimized on a circuit level, global equalization can then be applied to the entire array to compensate for room-related effects. This patented approach to system tuning has been specifically designed into the workflow of Performance Manager.

VTX’s patented SAFE suspension system is streamlined for speed and efficiency with improved hardware for faster setup with fewer pinning operations and greater security. A custom-designed protective cover and dolly makes transport easy and the suspension process fast, efficient and safe.

All suspension hardware is integrated into the enclosure and strategically positioned for fast and secure operation. Front flip hinges and captive rear hinge bars utilizing a unique Angle Stop Mechanism (ASM) allow for efficient assembly that is not only secure, but anti-rattle. Also included is provision for mounting a Laser Sighting Module accessory for greater ease and precision in array focus and system tuning.

The VTX Series complies with HARMAN’s GreenEdge initiative, combining environmentally friendly design with dramatic energy savings without compromising the excellent performance for which HARMAN products are known.

Like all JBL Professional products, the VTX Series is comprehensively tested in JBL’s power testing facilities. Unique in the industry, during the design phase JBL power testing submits each component and system to 100 hours of continuous, high level input, ensuring that your system will deliver extraordinary sound even after years of hard use and thousands of hours of performance.

“The VTX Series is a result of JBL’s continued effort to deliver more powerful, more compact, lightweight and flexible sound reinforcement systems,” Bauman commented. “JBL has invested heavily in the tools necessary to design, measure, evaluate and refine components throughout the development cycle. In addition to state-of-the-art CAD systems, we have developed proprietary R&D tools unique to JBL. With these tools, we are assured of meeting each product’s intended design goals, able to find opportunities for even better performance, and perhaps most important, have the resources to develop technologies that never existed. The VTX System is a premier example of this.”

Iconyx Helps St. Matthews Get the Message Across

Pacific Palisades, CA, January 2012….Nestled in the rolling canyons of Pacific Palisades, Saint Matthew’s Episcopal Church is one of the area’s oldest and largest parishes. The sprawling 42-acre grounds are home to multiple buildings including St. Matthew’s Day School and Pre-School, as well as recreational facilities and the highly acclaimed Moore Ruble Yudell-designed sanctuary.

While wonderful to behold, the sanctuary’s stunning architecture, with its soaring ceilings and exquisite glass work, has long suffered from problematic acoustics. As Daniel Bae, project manager for Sierra Madre-based Platt Design Group, explains, the room’s previous systems did little to alleviate issues of intelligibility and poor sound distribution. “A lot of the complaints about the previous systems had to do with speech intelligibility and coverage,” says Bae. “The room isn’t very deep, but it is very wide, so time alignment was a major problem.”

“When the sanctuary was first built, we had two speakers on the ceiling,” says Jeremias Mendez, the church’s Plant Manager for more than 30 years. “One side of the room was completely dead – people were only able to hear the sermon from a few seats.”

“It’s my understanding that the sanctuary’s architecture was designed to make the most of the choir and organ, and not the sermons,” observes parishioner Jim Dutka, the project leader behind the drive to upgrade the church’s audio system.

Dutka and company contacted Platt Design Group, who recommended a pair of Renkus-Heinz Iconyx IC-Live steerable arrays, one on either side of the proscenium. “The IC-Live enabled us to steer the sound where it needed to go – away from the walls and reflective surfaces and into the seats.”

Not surprisingly, aesthetics was also a major concern. “Renkus-Heinz provided custom paint for the IC-Live cabinets, helping them to blend almost invisibly into the sanctuary’s beautiful architecture,” says Bae.

“We have a number of older parishioners who have traditionally relied on hearing-assisted technology systems every week,” says Dutka. “Since we’ve installed the new system, many of them have come to us and informed us that they no longer need the assisted listening.”

“Platt Designs and Renkus-Heinz have provided us with a tremendous improvement,” agrees Mendez.

“I’m proud to say we now have one of the finest audio systems in the area,” Dutka concludes.

Toronto’s Prestigious National Club Modernizes Sound System with Renkus-Heinz

Toronto, CN – January 2012…   Hidden in plain view amongst the towering skyscrapers of Toronto’s downtown financial district, The National Club is one of the city’s most prestigious landmarks. The non-political members-only organization serves as private retreat for its clientele, including many of Canada’s current and future leaders.

Since its founding in 1874, The National Club has hosted a who’s who of important Canadian and foreign dignitaries. Today it serves as an esteemed venue for private meetings and dinners, weddings, presentations and club-hosted events.

The brick-and-plaster building has endured several renovations since being constructed in 1906. Most recently, the club’s Board of Directors voted to replace the Main Dining Room’s existing audio  system, with an eye toward better addressing the club’s requirements for high voice intelligibility and imrproved sound distribution.

The two-story, 1950 square foot Main Dining Room comfortably seats 200 people, with antique chandeliers hanging from its impressive 19-foot ceiling. A balcony is located to one side of the room, creating two alcoves directly underneath it.

According to Brock McGinnis of Westbury National Show Systems, Ltd., who designed and installed the new audio system, the building’s historic nature and 14″ thick brick-and-plaster walls presented some specific challenges during the installation.

“The room is a very reverberant two-story space, and the dinner guests create a great deal of noise,” McGinnis explains. “It’s very much like having dinner in the middle of a cathedral. The walls and ceiling are made of very hard surfaces, so in addition to the reverb problem we weren’t able to run any cable through the walls.”

McGinnis opted for an Iconyx digitally steerable array loudspeaker system by Renkus-Heinz. A pair of IC8-R columns are mounted on either side of the room’s motorized video screen. The high performance system provides superior sound pattern distribution technology combined with outstanding musicality and voice intelligibility.

“Renkus-Heinz was our first choice for The National Club,” says McGinnis. “We’ve used Iconyx loudspeakers on many other projects and find them to be extremely effective at steering the sound precisely where it’s needed, and away from areas where it isn’t. The quality of sound we get is excellent, even with all the hard surfaces in the room.”

Preserving the character and appearance of the club’s architecture was also paramount. The Iconyx loudspeakers fit very discreetly into the wall, rendering them barely visible.

“The National Club is so pleased with the Iconyx system’s sound quality and distribution technology that they want to install more Iconyx loudspeakers in other parts of the building,” McGinnis reports.

About MLA™ (Multi-cellular Loudspeaker Array)
The result of many years of intensive R&D, MLA’s methodology replaces trial-and-error array design with intelligent numerical optimization of the array’s output based on a highly accurate acoustic model. The multi-cellular format has six individual cells in each enclosure, each with its own DSP and amplification.

With up to 24 enclosures, each MLA array has up to 144 cells — too great a number to optimize manually, or by ear. Instead, Martin Audio’s proprietary Display2™ system design software automatically calculates FIR DSP filters for each cell and a redundant-ring audio network (U-NET™) downloads the settings into each array enclosure. Martin Audio’s VU-NET™ software provides real-time control and monitoring of the system.

MLA delivers a frequency response and SPL consistency never before achievable; a very high system output (140dB peak, per cabinet @1m); Automatic optimization of the array, both physically (splay angles) and electronically (DSP); Computer control and monitoring of the entire system, and total control of sound system balance for engineers and sound technicians.

MLA is fully integrated, with Class D amplification, DSP and U-NET digital audio
network built into each enclosure. MLA complete systems are ready-to-use, with MLA, MLD and MLX enclosures, flying hardware, software, cabling and training all supplied. Everything needed is included. All ancillary items — from tablet PC and Merlin™ controller to network interconnects and mains distro — are also included in the complete system package. This ensures full compatibility worldwide, down to cabling and accessories.

Additional features include 90° x 7.5° dispersion; a compact size (1136mm wide x 372mm high x 675mm deep), one-box-fits-all (festivals to theaters) application range and a global voltage, power factor corrected power supply.

MLA’s compact size and very high output allows it to be shipped using smaller trucks, offering considerable savings and reduced carbon footprint. The system also includes the MLX powered, flyable subwoofer capable of an unprecedented measured peak output of 150dB @ 1m; MLD downfill cabinet, and Merlin 4-in/10-out system controller and network hub. Audio input is via analog, AES3 or U-NET.

By adopting these principles and system components MLA is optimized for every member of the audience — from a 2,000 capacity theater, to a 20,000-seat arena, to a 100,000-person festival site. It will deliver the engineer’s exact mix to every seat (up to over 150 meters) with precision, exceptional power and clarity.

Rumor Has It: HARMAN’s JBL Loudspeakers Are a Hit at Philadelphia’s Newest Nightclub

NORTHRIDGE, California – It’s not a rumor: Philadelphia’s brand-new Rumor nightclub is a 10,000-square-foot venue featuring two dance floors, multiple oversized bars, private catering facilities and more—including a private VIP room called the Vault. Patrons can enjoy music from Rumor’s multiple sound systems, which include a variety of HARMAN’s JBL loudspeakers powered by Crown amplifiers, and controlled with BSS processing and HiQnet London Architect™ software.

“We needed to provide sound for a number of spaces that differed greatly in their sound reinforcement requirements,” noted Ian Hoffer of Aurora Sound and Light Design, which specializes in nightclub system design. “The Vault is an elegant, high-end room with velvet walls. One of the bar areas has a VIP cove at the end that needed audio. There’s an oval-shaped dance room that presented some challenges, and even the bathroom hallway had its particular acoustical requirements.”

The system in the Vault includes four JBL AC28 compact 2-way loudspeakers and two ASB6115 15-inch subwoofers. “This combination gave us all the sound coverage we needed without overly intruding into the space,” said Hoffer. “We used two Crown Macro-Tech i Series MA-5000i amplifiers to drive this system. The velvet walls in The Vault were put there as part of the room décor, not for acoustic reasons, but they actually provide a great acoustic environment.”

The Lev Room is an oval shaped dance floor with a DJ booth at one end. “We found by installing two JBL AM7215 high-power, 15-inch, 2-way, full-range speakers and two ASB6125 dual-15-inch subs gave us powerful sound with plenty of impact, yet without creating any acoustic problems that might have occurred considering the room’s oval shape,” Hoffer noted. “The DJ booth is equipped with two SRX712M 2-way, 12-inch stage monitors, which happen to work perfectly in this application, along with an ASB6115 subwoofer. The combination of the SRX712M monitors and ASB6115 sub in the DJ booth work perfectly together.”

To avoid any dead spots in the club, Hoffer chose six JBL Control® Contractor 322CT in-ceiling speakers and two ASB6125 subwoofers in the VIP cove at the end of the 40-foot long bar, and four Control 47LP in-ceiling speakers in the bathroom hallway. “We installed the Control 47LP speakers there so people could still hear what was going on in the main rooms while they were in the hallway,” Hoffer added. “The bar is quite striking, by the way, because it’s illuminated and constantly changes colors.” A Crown CTs Series CTs 3000 amp powers the VIP cove and hallway speakers.

“We used the Control 47LP and 322C in-ceiling speakers because I feel you get a fuller sound from them than from competitive models,” stated Hoffer. “They were easy to install with no mounting issues at all.”

All the audio signals for Rumor’s sound system are handled by a BSS BLU-160 signal processor with digital audio bus capability, augmented by four BLU-BOB2 breakout box output expanders. Control is provided by the BSS London Architect programming interface and HARMAN HiQnet software. “I had never used the JBL ASB subwoofers before this project – and I was very impressed with them,” said Hoffer. “Thanks to the London Architect setup and configuration macro for the ASB subs, we were able to get a great sound from them.”

“Everyone at Rumor is happy with the project,” Hoffer concluded. “The Vault is the newest and most popular Thursday night venue in Philadelphia and Rumor has been getting nothing but rave reviews.”

HARMAN’s JBL VERTEC® Line Arrays and ATK Audiotek Deliver An All-Out Performance at the 39th Annual American Music Awards

NORTHRIDGE, California – The 39th annual American Music Awards broadcast featured a star-studded lineup of artists, nominees and presenters including Taylor Swift, Jennifer Lopez, Nicki Minaj, Enrique Iglesias, will.i.am, David Hasselhoff, Christina Aguilera, Justin Bieber, Katy Perry, Kelly Clarkson and a host of others. Held at the Nokia Theatre LA Live on November 20, the American Music Awards (AMA) featured more than a dozen live performances, all heard through a sound reinforcement system comprised of HARMAN’s JBL VERTEC® line arrays.

ATK Audiotek of Valencia, California has worked on countless television productions, special events, conventions, installation and concert tours. For the AMA broadcast, ATK Audiotek brought in an audio system that included 70 VERTEC VT4889 fullsize line array loudspeakers, 15 VT4887 compact line array loudspeakers and five VRX932LA Constant Curvature loudspeakers. In addition, more than a dozen JBL VT4880A fullsize arrayable subwoofers that were already installed in the Nokia Theatre LA Live were employed for the live broadcast.

“With any live TV awards show, there are a number of specific considerations to deal with and the American Music Awards broadcast was no exception,” noted Mikael Stewart, VP of Special Events, ATK Audiotek. “A primary concern was that we had to make sure the house sound was loud enough–but also make sure that we didn’t intrude on the audio for the broadcast and overwhelm it with ambient noise.”

“In order to accomplish this, we went with JBL VERTEC mains and subwoofers,” Stewart added. “The VERTEC speakers give us more control over directionality, with fewer reflections off the theater’s walls and better accuracy in being able to cover all the seats. VERTEC’s focused coverage patterns are also an advantage in such a large venue, where reverberation and ambient noise can be a problem if you excite the room too much and don’t keep these factors under control.”

ATK Audiotek arranged the VT4889 speakers in eight clusters–four main arrays of nine, 10, 10 and nine speakers each, and four delay clusters of seven, nine, nine and seven each. In addition, five VRX932LA’s were placed under the balcony for additional coverage. The VT4880A subwoofers that were already installed throughout the theater were used to support the low end.

“Another very big advantage is that JBL VERTEC speakers are an industry standard and their performance capabilities are well known,” noted Stewart. “When we do these types of music awards shows, we can have something like 12 to 18 different artists and bands – and they all have their own sound engineers. It’s a big advantage for them to know the characteristics of the speakers that they are working with.”

“The Nokia is a very large and versatile ‘black box’ kind of theater,” Stewart pointed out, “and you can rig speakers just about anywhere in the room. There were no balcony hangs to contend with and it gave us more placement freedom than we’ve had in other theaters. Also, JBL VERTEC line arrays are lighter than most PA speakers, which adds to their rigging flexibility and the ability to place them at almost any angle.”

Broadway Music Redesigns Star Plaza Theatre’s Sound With HARMAN’s JBL VERTEC® Line Arrays

NORTHRIDGE, California – With a diverse event schedule featuring appearances by major touring artists, Merrillville, Indiana’s Star Plaza Theatre recently turned to Broadway Music to upgrade its sound system with HARMAN’s JBL VERTEC® line arrays. Star Plaza Theatre decided to make the investment after repeatedly needing to rent loudspeaker systems to accommodate the needs of larger productions. The new VERTEC system perfectly fills the 3,400 -seat venue with crystal-clear sound, from the main floor through to the mezzanine level.

Brian Wynn of Merrillville-based Broadway Music used his expertise, 25-year relationship with the Theatre and personal experience with JBL to provide Star Plaza Theatre with the best sound system possible. The main PA system features left-right arrays of eight VERTEC VT4888DP-DA midsize powered line array elements each, with a center array of three VRX932LAP powered Constant Curvature loudspeakers. VT4880ADP-DA powered fullsize arrayable subwoofers are hung three per side above the stage.

With a full schedule that also includes theatrical and orchestral productions, it was important to keep the subwoofers off the stage so they would not affect performances. Utilizing the self-powered speakers also pleased the engineers at the Star Plaza Theatre, as there was no need for additional amplifiers behind the stage.

“We’ve seen plenty of systems go in and out of the Star Plaza Theatre and we ended up at a point where there was no reason for the Theatre to continue renting or dealing with acts hauling their own VERTEC in, leaving the in-house system cold,” said Wynn. “Some of these bands already have saved settings for VERTEC so it’s almost a plug-and-play situation when they begin their setup and sound checks.”

“I could not believe that one of the best sounding venues in the world could sound even better,” said Mark Bishop, General Manager, Star Plaza Theatre. “The JBL VERTEC line arrays enhance the acoustically acclaimed Star Plaza Theatre to a whole new sound level. The folks at JBL and our friends at Broadway Music were a pleasure to work with throughout this project. The entire staff at Star Plaza Theatre is grateful, and I’m sure our audiences will appreciate the system for years to come.”

“The system sounds excellent,” Wynn concluded. “We have great coverage, even with the extremely high ceilings. There is definitely a significant difference in the performances and it is a positive one with JBL.”

Iconyx Makes the Grade in Missouri State University’s Carrington Hall

Springfield, MO – January 2012... Carrington Hall was the first building to open its doors on the Missouri State University campus in 1908, and has lived through many incarnations since then. Today Carrington Hall serves as the university’s administration building, and its previously unused, antiquated auditorium has been renovated and modernized.

To better serve the university’s needs, the auditorium has been converted into large multi-purpose classroom, to be used primarily for lectures but also to accommodate feature concerts, films and other special events.

MSU brought in Lenexa, KS-based acoustic and audio visual consultants Coffeen Fricke and Associates to design an audio system for the new multi-purpose classroom. As CFA’s Bob Ledo explains, the building’s stone and concrete architecture created an extremely reverberant environment, albeit a visually interesting one.

“The main seating area is a futuristic looking space designed with linear, angled florescent lighting on the underside of a gigantic cube that makes the large volume space more controllable, but also cuts off the view to the top of proscenium,” says Ledo. The room also features very low under-balcony seating space completely surrounded by concrete.

It proved quite challenging for Coffeen Fricke and Associates to find loudspeakers that would provide proper coverage in the hall’s main seating area as well as to the lower under-balcony seating.

“There was nowhere to put loudspeakers in the main seating area,” says Ledo. “We couldn’t use source clusters because the cube was in the way. Using surface mounted distributed loudspeakers would have been our least costly solution but definitely the least aesthetically appealing.”

The solution was found in the low profile Iconyx system from Renkus-Heinz. “We only needed two loudspeakers, which we shelf-mounted,” Ledo says. “They blend into the environment so well, they’re not recognizable as loudspeakers.”

The new audio system utilizes two self-powered Iconyx IC16-R line arrays located on either side of the stage. The room also utilizes a simple presenter podium with a gooseneck microphone and a wireless lapel mic, all driven by Biamp Audia DSP.

CFA associate John Hodgson used Renkus-Heinz RHAON DSP software to equalize the IC16-Rs. A Biamp Audia also provided very narrow parametric filters for room equalization and narrow banding, a technique CFA has used for many years.

“We were very successful in tuning the Iconyx,” explains Hodgson. “Feedback is a non-issue. We’re able to walk right in front of the Iconyx with a lapel mic, without any feedback.”

Ledo stressed that Carrington Hall’s new audio system is a fairly simplistic one. “Iconyx gave us the pattern control and directionality we needed, as well as satisfying the aesthetic requirements of the space. Everyone is extremely pleased with the results.”
